Common Troubleshooting Tips for Polymer80/80% Pistol Builds

Building your own functional pistol from an 80% frame and parts can be a very rewarding endeavor. It can also be frustrating when your new build doesn’t function flawlessly upon completion. In most cases, some minor fitting, polishing and adjustments will need to be made to have a reliable firearm. A functional pistol can break itself in under action, but tweaking things while you build does help move things along.

The parts we sell are intended for install by a licensed gunsmith. We cannot troubleshoot the issues you may run into when building or modifying things on your own. The links below are a good start to help resolve common issues, but are not comprehensive so performing your own research is strongly encouraged. Reddit, Youtube and Google are just a few places where you can find information on people who have come across, and resolved most issues.

We’ve compiled the list below on common troubleshooting and fitting steps. This list will be updated periodically.
